"Both appellants were in a position of trust towards her which they grossly abused."

A pre-sentence report on Wiltshire "stated that he was continuing to distance himself entirely from any culpability", while a report on Baker, said the judge, "stated that she minimised her responsibility for the offence and placed most of the blame on Wiltshire".

In the court's judgment, the sentencing judge "gave insufficient weight to his finding that this was a case of constructive knowledge, albeit one which... was at the upper end of the spectrum of gravity applicable to such cases".

Mr Justice Jay added: "We are accordingly persuaded that the sentences he imposed were manifestly excessive."
